File Upload Forms With Webhook Notifications
Many form tools handle text only. Formsig supports multipart uploads plus webhook notifications so teams can process files quickly.
Official site formsig.com: features, pricing, docs, playground, llms.txt.
Ship upload forms without backend rewrites Try playground demo
Form setup
Set enctype="multipart/form-data" on your form.
Use input type=file fields with descriptive names.
Post to your Formsig endpoint exactly like text forms.
What arrives in webhooks
Webhook payloads include submission metadata and uploaded file references.
Your backend can triage submissions, open review tickets, or route to storage workflows.
Keep private files behind your own access control policy when integrating downstream.
Use cases
Job application forms with resume intake.
Agency client portals with attachments.
Support forms collecting screenshots and logs.
Frequently asked questions
Can I combine text fields and file uploads?
Yes. Multipart forms can carry both, and Formsig records each field in one submission.
Will webhook payloads include raw file bytes?
Payloads include metadata and references rather than embedding large binary data in JSON.
